About CircuitHubCircuitHub is reshaping electronics manufacturing with The Grid—a factory-scale robotics platform designed to make small-batch, high-mix electronics assembly radically more efficient.
Think semiconductor-fab levels of precision applied to the chaotic world of prototyping and low-volume production.
The result?
A 10x throughput improvement in one of the world's most foundational industries.We've raised $20M from top-tier investors including Y Combinator and Google Ventures—and we're already profitable.
Our customers include industry leaders like Tesla, Meta, and Zipline.The Grid isn't a prototype—it's live, scaling fast, and already delivering real revenue.
We're now building the engineering core that will scale it further.What We're Looking ForWe're hiring driven Mechanical Engineers to join our automation team.
This role is focused on the design, development, and commissioning of automated robotic systems that support our advanced manufacturing process.Experience with fast paced mechanical design is essential, you must be confident with 3D CAD and have experience of designing and commissioning machined components as part of wider sub-systems.This role is perfect for an individual who loves to see their own designs through from concept, to build through to deployment.
You will be designing, prototyping, iterating and building systems constantly, working in a energetic environment amongst highly motivated peers.
You must have built things before, ideally robotics, whether as a hobbyist, student, employee or founder.Bonus skills:Exposure to PLC systems, particularly Beckhoff TwinCATProgramming and running CNC machineryDesign of chemical handling machineryExperience working with opticsWhat You'll doEvery day is different,



on a given day you could be doing anything from forklifting steel fabrications off a lorry and machining batches of parts to architecting machinery for new automation processes and liaising with suppliers.
Here are some examples of tasks you might get involved with:Design gantries and end effectors in Fusion 360Analyze end effector behavior from video recordings and revise its geometry to improve reliabilityConceive of novel mechanical systems to handle electronics partsInstall, commission and debug robotsManage supplier relationships to facilitate machine buildsTroubleshoot a wiring cabinet when a motor drive will not enableWork with build team members to ensure builds run smoothly, safely and quicklySpecifying a suite of sensors to ensure error detection during machine operationWhat CircuitHub can offerSalary, £45,000 - £100,000 dependent on experienceA candidate at the lower end of this range might have:Built some systems before with some exposure to robotics/automationExperience of working as part of a mechanical design team, seeing parts and subsystems through to manufactureA keen interest in transferring their career more towards practical roboticsKnowledge of design for manufacturing by machiningA candidate on the upper end of this range might have:Managed the build and deployment of large scale automated systems beforeExperience of PLC programming and debugging, particularly TwinCatExperience of design for a wide range of manufacturing methods from machining to sheet metal to injection moulding.Experience of technical mentoring of more junior engineersThink you can do more than this?
Great!
The salary range is not a hard limit, if you are an expert on all of the above we still want to talk to you.Not quite so experienced, but passionate and want to learn?
Also great!
Talk to us, we might be able to find a place for you.LocationThis is an onsite role out of our site in central Cambridge working alongside a driven team of automation engineers who are designing, building and supporting the expansion of our Grid PCB assembly system.
